SPECIFICA TION forming part of Letters Patent No. 767,508, dated August16, 1904.

Application filed December 11, 1902. Serial No. 134,795. (No model.)

To all whom, it nuty concern.-

Be it known that 1, PETER ALEXANDER VoGE'r, a sub ect of the GermanEmperor,

and a resident of Hanover, in the Kingdom of Prussia and Empire ofGermany, have invented certain new and useful Improvements in ShorthandType-Writing Machines, of which the following is a specification.

The invention relates to improvements in shorthand type-writingmachines. and has for its object to render it possible to take downnotes, words, phrases, speeches, and the like.

In the drawings, Figure 1 isa view showing the method of printing thecharacters at different relative positions with relation to a fixedline. Fig. 2 is a sectional end view of the type of printing mechanismused in the Hammond type-writer provided with my improved mechanism.

The mechanical construction of this short hand type-writer is secondedby a peculiar writing system founded upon principles similar to therules of stenography.

For the purpose of explaining the feature of the new machine I shallproceed to instance a few examples, by means of which it will be obviouswhich shorthand rules are employed in my improved shorthand type-writer.

The vowels are not always written, but frequently indicated by means ofa symbol in such a manner that by the elevation (higher position) of aconsonant the character e is indicated, by the low position (lowerposition) an 00, by a heavy-faced type the letter a, andso on.

In Fig. 1 of the annexed drawings several examples of such avocalization are given, which areso to be read: 1, been 2, book, 3, bar.Each one of these three characters is expressed by two letters only,thus rendering possible a great saving of time. Combinations ofconsonants frequently used for instance, st, sh, cr, ch-are combinedupon one key. Consequently in Fig. 1, read on: 4, steam; 5, shoe; 6,chalk. The words steam and chalk also need only two strokes, the wordshoe even one only. Prefixes and afiixes frequently recurring* forinstance, con, tionalso independent parts of speechfor example, and,

from, and so onare combined on one key alone. In this way it is possibleto produce the word constriction, which has twelve letters, on myshorthand type-writer by means of but four strokes of the keysto wit.,first, com second, str, in elevation, thereby expressing the characteri; third, 0; fourth, tion.

In Figs. 2, 3, and 4 three examples of mechanical constructions of thenew machine are shown.

Nearly every type-writer can be arranged for the present object by acorresponding modification or completion of its parts.

' In Fig. 2 a Hammond machine is chosen for example, wherein 1 indicatesthe wellknown type-shuttle; 2, the type-hammer behind the paper 3 to bewritten on. I 1 are the paper-conducting rolls. 5 is one of a series ofprinting-keys, which when pressed down causes a small letter to appear.Around the fixed pivot 6 swings a lever carrying the key 7. When key 7is struck, the free end 8 of this key-lever lifts the shaft 9 of thetype-shuttle 1 so far that instead of the small type 10 the large type11 comes in contact with the paper 3. So far the former arrangement ofthe Hammond machine has been left unchanged. For the purpose of theshorthand-writing machine, however, the capital letters 11 (initials)may be replaced by small heavy-faced letters.

The following arrangement serves for the purpose of adjusting thetype-shuttle 1 a little higher or lower, so that one can cause both thesmall type 10 and the large type 11 to be printed a little above orbelow the line, as will be seen from Fig. 1. Consequently thetype-shuttle of the Hammond machine formerly having only an elevationand a low position now has all in all six positions.

Around the pivot 6 referred to swings a three-armed lever 12 13 14:. Thelever-arm 13 is pushed upward when the key 15 is struck. When, however,the key 16 is pressed down, the lever-arm 12 is lifted. These movementsare accomplished by means of the levers swinging around the pivots 17and 18, as will be at once visible from the drawings. The three levers12 13 14, oscillating around pivot 6,

form a rigid device and by means of the connecting-rod engaging at arm14: transmit their rotations to the lever 19, swinging around the pivot8 and forming a solid whole with the cam 20. The position of the parts14 19 20 (shown in the drawings) is their central one. According as thecam 20 is raised more or lowered more the shaft 9, together with theshuttle-type 1, will be raised or lowered a little also. An exactdelimitation of this movement or stroke is attained by the elongation 21of the lever 6 8, which oscillates between the fixed points 22 and 23.

The keys are tapped in the following manner: As stated above, bystriking the key and pressing against the type a small letter of normalheight of handwriting is produced for example, the 1" in beer, Fig. 1,No. 1. hen, however, the keys '5 and 7 are tapped at the same time, theheavy-faced type 11 appearsfor instance, the b in the word bar, Fig. 1,No. 3. If 5 and are struck at the same time, the type-shuttle 1 sinksdown a little, because the key 15 through the medium of the intermediatelinks 17 13 1 1 19 transmits its movements to the cam 20, lowering thelatter, so that the shaft of the typeshuttle also goes down. Thisproduces, for Ln 1 u instance, the letter b of the word book, Fig. 1,No. 2. The same will be the case on a simultaneous tapping of the threekeys 5, 7, and 15 as to the heavy-faced type 11. A corresponding resultwill be attained when 5 and 16 or 7 and 16 are pressed down at the sametime, as the correspondingletter will then appear above the line ofwriting.

Having now fully described my invention, I declare that what I claim isIn a shorthand type-writing machine, the combination of an adjustabletypeshuttle, means for printing with said shuttle, a shaft on which saidshuttle is mounted, a lever for raising and lowering said shaft, a camon said lever, a shaft on which said lever is pivoted, a three-armedlever pivoted on said shaft, a rod connecting one of said arms with saidcam, levers connecting with said other arms and keys for operating saidlast-named levers.

In testimony whereof I affix my signature in presence of two witnesses.
